The Relationship Between Gait and Severity of Femoroacetabular Impingement

The Relationship Between Spatiotemporal Gait Parameters and Imaging-based Characteristics of Femoroacetabular Impingement (FAI) in Symptomatic Individuals

In this study, the spatiotemporal gait parameters of symptomatic femoroacetabular impingement (FAI) patients scheduled for hip arthroscopy are evaluated. Radiological measurements, including the Alpha angle (AA), Lateral Center-Edge Angle (LCEA), and Kellgren-Lawrence (KL) osteoarthritis classification, are recorded from patient files. The relationship between these radiological measurements and walking parameters is assessed. Additionally, the spatiotemporal gait parameters of FAI patients are compared with those of a healthy control group.

Walking assessments provide valuable insights into how Femoroacetabular Impingement (FAI) affects movement and aid in evaluating treatment outcomes. Research indicates that individuals with FAI experience reduced hip motion and slower walking speeds. By analyzing spatiotemporal gait parameters-such as gait velocity, cadence, step length, and vertical center of mass-the impact of FAI on walking can be better understood, leading to the development of targeted treatment strategies. The goal is to explore the correlation between these gait parameters and imaging-based FAI characteristics in affected individuals.

Study Overview

• Status: Recruiting
• Conditions: Femoroacetabular Impingement
• Intervention / Treatment: Other: Walking assesment

Detailed Description

Patients and control groups are compared using the paired samples t-test for parametric data and the Wilcoxon signed ranks test for nonparametric data. The relationship between gait parameters and imaging-based FAI characteristics is examined by calculating the Pearson correlation coefficient (r) for parametric data and the Spearman rank correlation coefficient (rho) for non-parametric data.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Patient with Femoroacetabular Impingement; Symptomatic femoroacetabular impingement patients scheduled for hip arthroscopy	Other: Walking assesment; Spatiotemporal walking assessments are performed using the Gait Analyzer app (version 0.9.95.0) on a smartphone. Participants who can walk independently without assistance walk a 25-meter path at their normal speed, with the smartphone securely attached to their body above the third lumbar vertebra using a belt. The app records gait velocity, cadence, step time, step length, and vertical center of mass for all participants.
Control group; Healthy indivicuals without Femoroacetabular Impingement	Other: Walking assesment; Spatiotemporal walking assessments are performed using the Gait Analyzer app (version 0.9.95.0) on a smartphone. Participants who can walk independently without assistance walk a 25-meter path at their normal speed, with the smartphone securely attached to their body above the third lumbar vertebra using a belt. The app records gait velocity, cadence, step time, step length, and vertical center of mass for all participants.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Gait velocity	Gait velocity, also known as walking speed, is a crucial parameter in spatiotemporal gait analysis. It refers to the rate at which an individual walks over a given distance and is typically measured in meters per second (m/s).	Baseline
Cadence	Cadence refers to the number of steps a person takes per minute while walking.	Baseline
Step length	Step length refers to the distance covered between two consecutive footfalls of opposite feet.	Baseline
Vertical center of mass	The vertical center of mass refers to the vertical position of the body's center of mass during walking. It is the point where the body's mass is considered to be concentrated and it fluctuates as the person moves.	Baseline
